may [1] be the missing piece of the puzzle?

[1] 
https://github.com/genodelabs/genode/blob/master/repos/gems/run/sculpt.run#L153

By convention, Sculpt labels the nic driver as "nic_drv". When the 
sculpt manager generates the <start> node for runtime, it uses this 
generic name as binary name. Also, the <policy> node generated for the 
nic router takes this name as key for selecting the network domain.

If the label does not match, the nic router leaves the uplink session 
unused because it has no matching policy.

To bridge the gap between the generic convention and the platform- 
specific driver name, the sculpt.run script uses the 'nic_drv' and 
'nic_drv_dtb' functions to rewrite the labels for the ROM sessions for 
the binary and dtb to the corresponding platform-specific names of the 
ROM modules at core.

Cheers
Norman
